Refrigeration Piping

Refrigeration components and the coil outlet hole are located to provide the best access for installation and maintenance. As the diagrams below indicates, the coil outlet hole is positioned forward on the right hand side of the case, fully visible in front of the fan plenum. An optional piping-to-top configura- tion can be ordered that runs the refrigeration lines through the top of the case at the location shown below. Note that on the narrow six door case an extra support is present on the end frames that requires case-to-case piping to be fed through the opening.

The expansion valve and other con- trols are located on the left-hand side of the case, are accessible without lifting the fan plenum, and may be reached by lifting only the left hand deck pan.

If it becomes necessary to penetrate the case bottom make certain it is sealed afterward with canned-foam sealant and white RTV.
